SFP, QSFP and CWDM/DWDM Transceivers — Optical Modules Tested Before Dispatch
This 630-item section is unusually concentrated: 55 suppliers, most of them specialised optical-module houses, offering SFP and SFP+ transceivers (305 positions), higher-rate optical transceivers and transponders (170), QSFP and XFP modules (54), optical distribution frames and panels (73), receivers and components. Distances run from short-reach multimode links to long-haul CWDM and DWDM modules covering tens of kilometres at 10G and above.
The business model in this niche matters more than the country of origin: serious module suppliers code each transceiver for the buyer's switch platform, test it in real equipment before shipping, and document optical power and sensitivity per serial number. Russian optical houses follow exactly this practice, serving domestic carriers and data centres, and their export pricing sits well below Western brand modules of equal specification — a difference that scales fast when an ISP buys hundreds of optics a quarter.
- SFP/SFP+: 1G and 10G modules in standard wavelengths, reaches and DDM support
- WDM: CWDM and DWDM optics for fiber-lean backbone and metro links
- 40G/100G: QSFP-class modules for aggregation and data-centre interconnects
- ODF: distribution frames and patch panels to terminate the fiber plant
- Logistics: grams per unit — courier delivery worldwide in roughly a week
